Every vessel has a body.
Now it has a brain.

A nervous system for your fleet. Daily noon reports flow in as sensory signals. Physics turns them into knowledge. Knowledge becomes defensible outcomes and decisions, made before you spend more than you should.

The condition

A ship that doesn't think for itself is leaking money it can't see.

Every hull degrades. Every day a vessel sails, a fraction of its fuel is paying for fouling rather than progress. That fraction is invisible to most operators. It surfaces at drydock, eighteen months too late, on a bill nobody planned for.

The data is already there. Your crew is already filing it. What's missing is a system that turns those noon reports into knowledge, and knowledge into defensible outcomes and decisions, made before you spend more than you should.

The infrastructure

Four layers, one continuous signal.

Each layer reads from the one before and feeds the one after. Sensory input enters at the bottom; defensible outcomes and decisions exit at the top. Nothing is bolted on. The platform was built as a single nervous system from day one.

INPUT · daily noon reports · AIS positions · sea-trial baseline · weather

Sensory · diagnostic

Burning Intelligence

Where is every ton of fuel actually going?

Physics-informed models track daily fuel oil consumption and attribute every ton to its physical cause: ME load, auxiliaries, weather, draft, trim, hull degradation, propeller residual. Reported consumption is compared against a theoretical baseline derived from the vessel's own sea-trial.

Hull Intelligence

How fouled is the hull, and what is it costing?

A hull fouling index updated daily, with historical degradation severity anchored to ISO 19030 and the ITTC kS roughness scale. Drydock-aware trajectory modelling forecasts the fuel cost of the hull through the next drydock window, so cleaning decisions stop being guesswork.

Retrofit & Finance

Which retrofit actually pays back, and by when?

New resistance and economic models test the operational effectiveness and ROI of hull, propeller, and energy-saving-device retrofits. Each candidate is scored with full regulatory impact analysis (CII, EEXI, FuelEU Maritime), so the savings calculation includes the regulatory cost most reports leave out.

Decision Support

Today's standing order, with the physics and the money behind it.

Operational recommendations and standing orders derived from the three layers above, each explainable along three axes: money (€/day), engineering (physics rationale), and law (regulatory and compliance). LLM infrastructure is scoped to each client's fleet history, so recommendations carry your operating context, not a generic playbook.

Behind NavalBrain

Built by the engineers who'd have to defend it.

NavalBrain is led by Nikolas and Nearchos Fournaris, both Naval Architecture & Marine Engineering graduates of NTUA, with Anthia Christou (Economics, AUEB) translating the engineering into real money. The team writes the physics, the code, and the contracts.
